Vienna has several X-mas markets. The most famous just outside the Town Hall, usually there is an ice rink there as well. Lots of arts and crafts, toys, fabrics, etc lots of mould wine, roast chestnuts, very romantic. Another one is more arty (Spittelberg), more jewellry and that type of stuff. There's also markets outside the Schoenbrunn castle, and other sights. Have a look [broken link removed], it's only in German, but google translate does a good job, but more importantly, lots of pictures so you get the idea.
